the phenylthiourea-substituted triethoxysilane as a silane agent was synthesized and grafted on highly ordered nanoporous silica (lus-1) with a textured morphology and hexagonal array. this material (tu-lus-1) contained 0.8 mmol/g of soft base phenylthiourea group and surface area 760 m2g-1 and was able to adsorb 0.75 mmolhg/g of tu-lus-1 in endothermic reaction.

This review presents an overall discussion on the morphology analysis and optimization for perovskite (PVSK) solar cells. Surface morphology and energy alignment have been proven to play a dominant role in determining the device performance. The effect of the key parameters such as solution condition and preparation atmosphere on the crystallization of PVSK, the characterization of surface morp...

TiO2-SiO2 photocatalytic nanostructure film on windshield for self-cleaning purposes was prepared via sol–gel dip-coating method. TiO2 films were prepared on automotive glass pre-coated with a SiO2 layer by a dip-coating method followed by annealing at 500 °C for 30min. The films were characterized using X-ray diffraction XRD and scanning electron microscopy SEM, FE-SEM techniques. The TiO2-SiO...

Background: Selection of human spermatozoa prior to assisted reproduction is currently based on motility and morphology. Recently, Zeta method has been introduced for normal sperm selection based on sperm surface charges. In addition, one of the features of apoptosis is the externalization of phosphatidylserine (PS), which are normally present on the inner leaflet of the sperm plasma membrane. ...

When a drifter is trapped in an eddy, it makes either a cycloidal or a looping trajectory. The former case takes place when the translating speed is larger than the eddy spinning speed. When the background mean velocity is removed, drifter trajectories make loops. Thus, eddies can be detected from a drifter trajectory by identifying looping segments. In this paper, an automated scheme is develo...

In order to strengthen the prediction of rockburst and inquire the relationship between the rockburst proneness of rock and its surface fractal characteristic, the surface fractal of the rock was studied by fractal method and uniaxial compression test. The change rules of surface fractal of different types of rock were compared by calculating its fractal dimension of rock before experiment and ...

With the popularization of precision-machining process by the hard tooth-surface gear, special machining tools have also been developed rapidly, which is mainly manifested in as aspects as the application of new materials and cutting tools’ coating technology, the mature of ultra-hard-grain CBN tools’ preparation technology, and the pefecting day by day of tool-structure design and tool-integra...

We use a mathematical morphology approach to compute the surface and curve skeletons of a 3D object. We focus on the behaviour of the surface skeleton, in particular the reversibility for the case when the skeleton is, and is not anchored to the set of centres of maximal balls. We elaborate on the difficulties to obtain a reversible surface skeleton that does not depend on the orientation of th...

Introduction: Arabia Terra, with an area of ~1x10 km [1] centered at (25E, 5N), is an anomalous region along the Martian dichotomy. Traditionally considered part of the ancient southern highlands, Arabia Terra is a transitional province between the southern highlands and northern lowlands in both topography [2] (Fig. 1) and crustal thickness [3]. While the geological processes leading to the fo...

A problem of interest in digital video edition is the elimination of moving objects from one video and the introduction of pieces of other videos in their places. A fundamental problem to build computational tools for this purpose is the segmentation of moving objects. This paper approaches this problem by a new technique, based on Beucher-Meyer's paradigm, with markers detected by morphologica...
